Palmer's Pure White-Fish Meal

A rare Chad Valley advertising puzzle. Of interest due to its circular shape which depicts six sectorial pictures describing the process of making and marketing George Palmer's feeding meal from catching the fish, processing and final use on farms.
This design pre-dates the start of Waddington's well-known range of 'Circular' puzzles and it is not known if this puzzle gave them this idea.
A critical difference is that in this puzzle the text is above each picture around the its top whereas Waddington's text is below each picture and around the base.
The example illustrated has two replacement pieces and was originally owned by Tom Tyler who also published a description in his 2017 book of CV Promotional Puzzles.
